Problems with rtl.css

hello

rtl.css has some problems for my website
for example:
some plugins conflict with this ,so layout was ugly!
and very important problem is here:
when number of words in budypress menu navigation was more than a special number,in normal css
this character(>) solve the problem but in rtl css , (>) don’t exist ,so last words are hiden and never shown !

thanks for reply.
